undefined reference to `void backend::addLabelToPointCloud<resources::VoxbloxColorPointCloud>(unsigned int, unsigned long, resources::VoxbloxColorPointCloud*)'

[Mysterium-sch]

I am trying to run maplab 2.0 on 20.04 noetic. To install the python packages I had to change python to python3. When i go to build maplab the maplab console fails due to the following error: undefined reference to `void backend::addLabelToPointCloudresources::VoxbloxColorPointCloud(unsigned int, unsigned long, resources::VoxbloxColorPointCloud*)'

I was wondering if anyone else has seen this issue. I have provided my catkin config below.

I meet this problem too. Do you have some idea how to solve it?

I temporarily skip this problem by comment "addLabelToPointCloud(label, point_idx, output_cloud);" in "src/maplab/backend/map-resources/include/map-resources/resource-conversion-inl.h" 😂
